Ring terminal, Ergom KRA 70 / 12 mm, sealed aluminium (E12KA-01010101700)

Sealed ring terminal Ergom KRA 70 / 12 mm is an aluminium-constructed electrical connector designed for reliable cable termination. The terminal accepts conductors sized to the KRA 70 specification and attaches to a 12 mm stud to create a mechanically secure, hermetically sealed connection. Its sealed design provides protection against moisture, dust and environmental contaminants, while the aluminium body offers corrosion resistance and lightweight performance suitable for a range of installation environments.

Advantages

The sealed aluminium construction combines corrosion resistance with reduced weight compared to heavier metals. The hermetic sealing around the conductor entry minimizes ingress of water and dust, improving long-term contact reliability in exposed environments. The ring termination ensures a stable mechanical connection to a 12 mm stud, reducing the risk of loosening under vibration. The terminal is compatible with conductors matching the KRA 70 cross-section, enabling straightforward installation and consistent electrical contact.

Suitable for

• Automotive battery and chassis grounding points where a sealed connection is required
• Industrial machinery and control panels exposed to dust or splash
• Marine electrical systems subject to humid or corrosive environments
• Repair and retrofit projects requiring a durable, lightweight ring connector

Key specifications

• Material: Aluminium body with sealing element
• Conductor cross-section: Intended for KRA 70 size conductors
• Stud size: 12 mm ring bore
• Connection type: Sealed ring terminal for crimp termination
• Environmental protection: Hermetic sealing against moisture and dust
• Mechanical: Designed for vibration-resistant fastening to studs

How to use

Strip the conductor insulation to the length appropriate for the terminal’s barrel, insert the conductor fully into the barrel, and ensure the sealing element surrounds the insulated cable entry. Crimp the barrel using a suitable crimping tool sized for the KRA 70 conductor to achieve a secure mechanical and electrical connection. Place the ring over the 12 mm stud and fasten with the appropriate nut ensuring a tight, vibration-resistant assembly. Verify the seal integrity and the mechanical tightness after installation.

Usage recommendations

Use a calibrated crimping tool matched to the conductor size for consistent crimps; inspect crimps visually and, where appropriate, by pull test. For marine or highly corrosive environments, ensure mating hardware is corrosion-resistant and periodically check the connection for signs of degradation. Do not exceed the conductor sizes or stud diameter specified for this terminal to maintain mechanical and environmental performance.
